Re: Sharp LED TV flashing green 2x per second - LC-70LE735X, DPS-222BP, RUNTKA857WJQZ
With jumper wires on:
PD-15 (BU5V) ----- 14 PS_ON ( turn on UR13.2V )
PD-15 (BU5V) ----- 16 PNL_POW (turn on PNL12V )
PD-15 (BU5V) ----- 24 (STB) ( turn on BL_ on ) IC7700
PD-15 (BU5V) ----- 21 OFL
*PD-15 (BU5V) ----- 19 Dimmer (983ohm resistor)
PD Connector:
PD-1 (PNL12V) : 11.92V
PD-2 (PNL12V) : 11.92V
PD-3 (SGRN) : 0V
PD-4 (SGRN) : 0V
PD-5 (UR13.2V) : 13.05V
PD-6 (UR13.2V) : 13.05V
PD-7 (UR13.2V) : 13.05V
PD-8 (UR13.2V) : 13.05V
PD-9 (SGRN) : 0V
PD-10 (SGRN) : 0V
PD-11 (SGRN) : 0V
PD-12 (SGRN) : 0V
PD-13 (AC_DET) : 3.27V
PD-14 (PS_ON) : 4.95V
PD-15 (BU5V) : 4.95V
PD-16 (PNL_POW) : 4.58V
PD-17 (NC) : 0.04V
PD-18 (NC) : 0.04V
**PD-19 (DIMMER) : 4.55V**
PD-20 (NC) : 0.04V
*PD-21 (OFL) : 1.74V*
PD-22 (ERROR) : 0V
PD-23 (NC) : 0.04V
PD-24 (SBY) : 4.3V
Added PD-15 to PD-19 with 983ohm resistor and read 4.55V, and value of PD21 changed from 0V to 1.74V.
Still the same - screen flashes for a split second then off.
